Description
Technical field
The present invention relates to machining device, be specifically related to the wire rod shear of the cam calibration of automation.
Background technology
In current mechanic factory workers both domestic and external, often encounter such problem, i.e. the equidistant cut-out of metal wire rod, such as, on construction site, often will cut off reinforcing bar, in order to needs various on construction site.
If design one can stretch to metal wire rod, again can quick equidistant cut-out, a lot of enterprise thirsts at present just.
Summary of the invention
The present invention is directed to above-mentioned existing problems, can stretch to metal wire rod, again can a kind of mechanical device of quick equidistant cut-out.The occasions such as metal wire rod factory, construction site, machining factory can be applied to widely.
The technical solution that the present invention relates to:
As shown in Figure 1, the wire rod shear of the cam calibration of automation, is characterized in that: this device is made up of firm banking 1, fixed pulley 2, wire rod 3, aligning roller 4, cam protractor 5, motor 6, big belt pulley 7, belt 8, cam protractor power shaft 9, punching machine type cutting machine 10, chain 11, big roller 12, trundle 13, supporting steel plate 14, middle belt pulley 20, punching machine type cutting machine power shaft 21, small belt pulley 22, decelerator 23, cutting knife 24, fixing parallels 25; Wherein supporting steel plate 14 and firm banking 1 are by pinned connection, and make supporting steel plate 14 can do 360 degree around bearing pin and horizontally rotate, fixed pulley 2 is arranged on supporting steel plate 14 by fixed axis, and wire rod 3 is looped around on fixed pulley 2, and aligning roller 4 is horizontally disposed; Cam protractor 5 is arranged on a side of wire rod 3, and punching machine type cutting machine 10 is also arranged on the same side of wire rod 3, makes big roller 12 during installation directly over wire rod 3, and trundle 13 is arranged on immediately below wire rod 3; The center of big belt pulley 7 and cam protractor power shaft 9 are arranged on same straight line; Center and the punching machine type cutting machine power shaft 21 of middle belt pulley 20 are arranged on same straight line; Chain 11 is arranged on the below of punching machine type cutting machine 10; Small belt pulley 22, decelerator 23, motor 6 are arranged on same straight line; Small belt pulley 22, big belt pulley 7, middle belt pulley 20 are arranged in same plane; Cutting knife 24 is arranged on punching machine type cutting machine 10, and fixing parallels 25 is arranged on cutting knife 24 1 side.So that cutting knife 24 pairs of wire rods 3 cut off.
Be illustrated in figure 2 the cutter structure schematic diagram of punching machine type cutting machine 10 of the present invention; Cutting knife 24 is arranged on punching machine type cutting machine 10, and fixing parallels 25 is arranged on cutting knife 24 1 side.Between the cutting knife 24 of described punching machine type cutting machine 10 and fixing parallels 25, gap is 0.2 ~ 0.6mm.
The further technical solution of the present invention is:
Described belt 8 is synchronous cog belt.Synchronous cog belt can make between belt and belt wheel non-slip, thus can transmit the gearratio of steady.
Described cam protractor 5 is transposition circulation protractor and station number is 2, and namely the transposition circulation of cam protractor 5 is: rotate and---stop---rotation---to stop.Station number is 2 is that when cam protractor 5 is in stopping, cutting knife 24 pairs of wire rods 3 cut off in order to coordinate wire rod 3 to stretch and cut off.
Described decelerator 23 is Two Grade Column Gear Reducer.The rotating speed that motor 6 exports is after Two Grade Column Gear Reducer slows down, and torque obviously strengthens, and can increase cutting knife 24 pairs of wire rod 3 cutting force.
Described motor 6 is synchronous AC motor.The feature of synchronous AC motor is: during steady-state operation, has constant relation, i.e. n=60f/p between the rotating speed of rotor and mains frequency, and wherein f is mains frequency, and p is the number of pole-pairs of motor.If the frequency of electrical network is constant, then during stable state, the rotating speed of synchronous motor is permanent is constant and haveing nothing to do with the size of load.Be conducive to the wire rod 3 cutting different thicknesses like this.When wire rod 3 is thicker, cutting force is inevitable large, and now motor 6 does not slow down because resistance is large, does not slow down, and does not just affect the stretching of cam protractor 5 pairs of wire rods 3.
Cutting knife 24 material of described punching machine type cutting machine 10 is high-speed steel.High-speed steel is also known as high-speed steel (or being white steel), and the most frequently used trade mark is: W18Cr4V, and other also have a lot of trade mark.Be that it also contains with the difference of carbon steel: the alloying elements such as chromium (Cr), tungsten (W), nickel (Ni), vanadium (V).High-speed steel is a kind of tool steel with high rigidity, high-wearing feature and high-fire resistance, also known as high-speed tool steel, is commonly called as Bai Gang.High-speed steel is that Taylor F.W. of the U.S. and M. White made in 1898.The processing performance of high-speed steel is good, shock-resistant, intensity and toughness coordinate also fine, and therefore the present invention is used for manufacturing cutting knife 24.
Described big roller 12 and trundle 13 surrounding are with circular groove, and groove radius 0.5 ~ 0.8mm less of the radius of wire rod 3, be conducive to the stretching of wire rod like this.
The bottom of described fixed pulley 2 is provided with roller, and fixed pulley 2 can regulate with the distance of cam protractor 5.Be conducive to like this adjusting the spacing of fixed pulley 2 and cam protractor 5 to adapt to the needs of the wire rod 3 of different thicknesses, such as when wire rod 3 is relatively thicker, the spacing of fixed pulley 2 with cam protractor 5 can be adjusted far, come so that wire rod 3 is fully unfolded.
Described wire rod 3, aligning roller 4, big roller 12, trundle 13 are arranged in same plane.Favourable like this wire rod trouble-free operation.
Between the cutting knife 24 of described punching machine type cutting machine 10 and fixing parallels 25, gap is 0.2 ~ 0.6mm.Gap length can sight line material 3 thickness be determined, and when wire rod 3 is thick, just selects gap larger, otherwise just selects gap smaller, favourable like this wire rod property cut.
Beneficial effect of the present invention:
One, adopt the present invention can be stretching fast and cut off metal wire rod, automaticity is high, metal wire rod is cut off and is accurately put in place, productivity ratio is high, serialization cut off mass ratio manually cut off improve a lot, the present invention adopts cam protractor to carry out wire stretching, the position length error≤± 1mm of wire rod after cutting off.
Two, delicate structure of the present invention, adopts synchronous AC motor, good stability, little by load effect.Precise control, easy to maintenance, equipment manufacturing cost is moderate, safe and reliable, has certain economic and practical value.
Three, the present invention has wide popularizing application prospect, can be widely used in building enterprise, and construction site, wire rolling plants, machining factory, bridge construction is on-the-spot, automaticity is high, saves a large amount of manpower and materials.
